Usage Note
Formal is an invariable adjective for masculine and feminine singular (un trato formal, una reunión formal); the plural adds -es: formales. Beyond 'formal in register', it also means 'reliable' or 'serious' in colloquial Spanish: es una persona muy formal (he/she is a very dependable person) — a nuance English 'formal' lacks. The noun is formalidad and the adverb formalmente.
Examples
"La reunión requería un ambiente formal."
Natural Translation
The meeting required a formal atmosphere.
